It’s the vitamin that we get from the sun, yet despite its ample availability, one in three Australian adults still suffer from mild, moderate or severe vitamin D deficiency.

Now, new research from the University of South Australia gives strong evidence that vitamin D deficiency is associated with premature death, prompting calls for people to follow healthy vitamin D level guidelines.

Published in Annals of Internal Medicine, the study found that the more severe the vitamin D deficiency, the greater the risk of mortality.

Vitamin D is an important nutrient that helps maintain good health and keep our bones and muscles strong and healthy.

First author and UniSA PhD candidate, Josh Sutherland, says while vitamin D has been connected with mortality, it has been challenging to establish causal effects.

“While severe vitamin D deficiency is rarer in Australia than elsewhere in the world, it can still affect those who have health vulnerabilities, the elderly, and those who do not acquire enough vitamin D from healthy sun exposure and dietary sources,” Sutherland says.
